CIGAR-BUNCI-I MACHINE.

Application filed VFebruary 7, 1925. Serial No. 7,482.

Our invention relates to an improvement in cigar bunch machines and moreparticularly to improvements in the mechanism for effecting the transferof binders from the cutting mechanism to the rolling table.

Cigar bunch machines, and especially those of the automatic type, haveheretofore been provided with mechanism adapted to effect the trimmingor cutting of a leaf of tobacco to form a binder adaptable for rollingabout a filler to form a bunch, and -in cooperation with such mechanisma device for transferring the binder yfrom the cutting mechanism tosuitable rolling mechanism, as a rolling belt, for its application to afiller supplied to the rolling mechanism.

Such mechanism as has heretofore been utilized for this purpose, whileof a substantial degree of leliiciency, has been found to be notentirely satisfactory in operation and of undue complication instructure and adj ust-ment.

'More particularly, such mechanisms have been found to be unsatisfactoryin that the transferring devicein delivering the binder to the rollingbelt has a tendency -to overreach the predetermined point of -deliverydue principally to the effect at the end of the transferring` arm ofthesum ofthe lost motions in its opera-ting mechanism. Further, suchmechanisms are so constructed and operated as to require an undue amountof space and so as to be a source of possible accidental injury to anoperator.

Now it is the object of ouil invention to provide mechanism of ltheabove indicated characteristics which will be of a high degree-ofeicienc'y in operation, simple in construction and of adjustment,economical of space and proof against accidental injury to an operator.

Having now indicated in a general way the nature and purpose of ourinvention, we will proceed to a detailed description thereof, withreference to the accompanying drawings, in which there is illustrated apreferred embodiment, and in which- Fig. l is a plan view .of a portionof a cigar bunch machine embodying our Vinvention.

Fig. 2 is a. side elevation, partly in section, of the subject of Fig.l.

Fig. '3 is a sectional `view on line S-f-, Fig. 2.

Fig. t is an enlarged cross-section on line M, Fig. l.

a indicates the frame of a cigar bunch m-achine on which is mounted arolling table b; The rolling table is provided with longitudinal groovesc in the bottom of which are perforations affording communication with abox d, which is continuously connected to a source of suction through apipe e. Adjacent one endb of the table is a take-up roller f for arolling apron (not shown) adapted to be supported by the table: gindicates a rolling bar supported on a sliding carriage and adapted toactuate the apron to effect the application of the binder to the llerand roll the bunch. Adjacent. to the rolling table is a paster Iz,provided with a pasteapply-ing wheel z' adapted to be actuated lfor theapplication of paste to a binder positioned on the rolling table.

The mechanism for cutting or forming the binder is carried by a bracketprojecting from an air box lc secured to the frame a and within whichare two air chambers c, lc, .connected with a. source of suction throughvalves to be` hereinafter described. On the bracket is secured an outerhollow shell Z provided with a row of perforations mA and extendingabout a vertically positioned knife blade n. lVithin the knife blade isa hollow inner shell o the upper surface of which is perforated andattached by means of a screw to the upper end of a stem p, as shown inFig. l. rIhe lower end of stem p rests upon the end of an adjustable pinu threaded in one arm of a pivoted lever c. The upper surface of theinner shell, While normally lying vflush with the edge of knife n', isadapted to be raised above and lowered beneath the cutting edge thereofand lfor this purpose the other arm of lever o is provided with a camfollower' adapted to follow .a cam surface w formed on the side of a camdisc t and normally arranged to maintain the lever at rest with theupper surface of the inner shell lying flush with the cutting edge ofthe knife, but having a low section and a high section which causes thelever o to be oscillated, resulting in raising or lowering the surfaceofthe shell with respect to the knife edge.

Communication is afforded between the inner shell c and the Vouter shellZ through an aperture vin the knife blade and `they are in lOO .communication with air chamber 7c, comu munication between which and asource of toY ' cam groove formed in a cam disc 9.

knowntype, adapted to cooperate with theV knife blade n to eiect thecutting of a binder out Vof aleaf supported by shells o and fm. To thelower end of the shaft is secured a pinion 6,V adapted to mesh with asegmental gear 7, formed on one arm of a pivoted lever 8, the other armof which is provided with a cam follower engaged in a the cam disc isrevolved, the lever 8 is oscillated, causing the roller mechanism toV beoscillated back and forth over the knife blade, the inner Ashell beingthen below the edge ofthe knife. Y

The mechanism for transferring the binder from the cutting or formingmechanism, above described, to the rolling mechanism comprises a hollowvertical shaft 10 mounted in a stand 11 mounted on the frame a: andhaving secured to its upper end a horizontally extending arm 12, therebeing communication between the interiors of the shaft and arin. Ahollow transfer shell 13.

the bottom of which is perforated, is rotatably secured at the free endof the arm and is in communication with the interior of the arm througha neck 14. Adjacent its upper end the shaft 10 is provided with agrooved collar 15 in which engage keys 16 formed on a bracket 17. A rod18, which is slidably mounted on stand 11, is pivotally connected at itsends to thetransfer shell 13 and the bracket 17,'thereby providing aparallel motion for transfer shell 13. p

The lower end ofthe shaft is reduced and threaded foi-,the reception ofa nut which serves to support an abutment 19 for one end of a spiralspring 20 through which the shaft passes and the other end of whichbears on the frame. The lower end of the shaft rests on adjustable pin21 in one arm of a, pivoted lever 22, the other arm of which is providedwith a cam follower engaging a cam 23, by the action of which the shaft10isy moved up vertically againstthe action of spring 20 which, whenpermitted by the cam, returns the shaft. A'segmental gear 2li is mountedon the shaft 10 adjacent its lower end and meshes with a segmental gear25 on the end of a pivoted lever 26. The lever 26 is adapted to beoscillated by a link 27, one end of which is connected to lever 26 bymeans vWhen of a slot and pin connection and which is adapted to bekoscillated by means of a cam disc 28, through a cam follower 29.Oscillation of lever 26 is transmitted to shaft 10, which results in'the swinging of arm 12- being turned on a vertical axis by means of theparallel motion including rod 18.

The interior of shaft 10 is connected to air box Ze through a passage30, communication being controlled by a valve 31 adapted to be actuatedby a pivoted lever 32, one arm of which engages ythe stem of the valveand the other arm of which is provided with a cam follower adapted tofollow a cam surface 33, which oscillates the .lever to open the valveagainst the action of its spring, which closes it when the cam permits.

The operation of the device will, it is believed, be readily understoodif it be premised that the rolling tablel is constantly under suction,the transfer shell 13 is placed under suction and the suction relievedby the'opening and closing of valve 31, and the inner shell o and outershells Z yare placed under suction and suction relieved on bothsimultaneously by the opening and closing of valve y. The arm 12 andshell 13 are swung about the axis of the shaft l10 by the oscillation oflever 26 and they are raised and lowered vertically bythe oscillation oflever 22. The jaw 5 for the support of roller mechanism is swung' on theaxis of its supporting shaft by the oscillation of lever 8.

The several cams adapted for the actuation of the several elements ofthe device are arranged so that the several elements are actuated intimed relationship as follows:

Vith suction on the shells Z and 0` and the two shells lying in thesaine plane, an operator places a tobacco leaf over the knife blade, theroller mechanism is advanced and the inner shell depressed, resulting inthe cutting out of a binder from the leaf. .fis the roller mechanism isretracted, the arm 12 has been swung to position'the transfer 13 overthe inner shell, the transfer having been turned to align with the innershell by the action of rod 18. Shaft `10 is then lowered resulting inlowering the shell 13. At the same time the inner shell 0 is raisedabove the knife and the binder presented to the underside of thetransfer shell. Suction now goes off the inner and outer shells and onthe transfer shell resulting in transference ofthe binder from the innershell to the transfer shell.

The shaft 10 is then lifted, lifting the shell 13, and the inner shellreturned to normal in plane with the outer shell Z. The arm is thenswung in a horizontal plane to position the shell 13 over the rollingtable, the shell being` turned to proper position by the action of rod18. The shaft l0 is then lowered and the binder presented to the rollingtable by the shell. Suction then goes off the shell and the suction onthe rolling table causes a transference of the binder.

Having now fully described our invention, what we claim and desire toprotect by Letters Patent is:

In a cigar bunch machine, the combination with a binder cutting deviceand a rolling table, of an arm mounted on a vertical pivot, means forthe support-.of a binder pivotally mounted on said arnn means t-o swing`said arm in a horizontal plane, a link paralleling said arm andpivot-ally secured at one end to said support for a. binder and Xedmeans pivotally engaged with the other end ot said link whereby whensaid arm is swung said support will be turned through the medium of saidlink.

In testimony of which invention, We have hereunto set. our hands, atPhiladelphia, Pennsylvania, on this 21st day ot' January, 1925.
